Abstract
Abstract A jumping hoop has a rigid U-shaped member which is held in the hand. A light flexible member is adjustably connected to opposite ends of the rigid member, forming a hoop. Ends of the rigid members are reentrantly bent to hold ends of the flexible member telescoped therewith. Ends are held together by an elastic band which jams between the sliding telescoping members in one construction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
251 words
An adjustable jumping hoop apparatus comprising a first elongated member bent in a U-shape having a cross portion and two leg portions, the leg portions terminating in a first pair of spaced elongated distal sections, a second elongated uniform tubular member bent in a complementary U-shape having a cross portion and two leg portions which terminate outwardly in a second pair of spaced elongated distal sections, the first pair of distal sections having relatively rigid joint means for connection to the second pair of distal sections, and the second pair of distal sections having flexible resilient joint means for telescopically joining the relatively rigid joint means of the first pair of distal sections, thereby holding the first and second elongated U-shaped members together in a jumping hoop of a selected size, wherein the rigid joint means comprises elongated elements and wherein the flexible joint means comprises elongated rigid tubes having segmental openings spaced from ends of the tubes and having flexible round resilient bands circumferentially surrounding the tubes at the segmental openings and extending into the segmental openings, the elongated elements of the first rigid joint means being positioned in the tubes, the bands extending through the segmental openings to engage the elements, whereby relative longitudinal movement of the first and second joint means frictionally draws portions of the bands from the segmental openings to positions between the elements and inner walls of the tubes, tightly wedging the elements in the tubes, against further relative axial movement in the same direction.
Claim 2
Dependent Claim
251 words
An adjustable jumping hoop apparatus comprising a first elongated member bent in a U-shape having a cross portion and two leg portions, the leg portions terminating in a first pair of spaced elongated distal sections, a second elongated uniform tubular member bent in a complementary U-shape having a cross portion and two leg portions which terminate outwardly in a second pair of spaced elongated distal sections, the first pair of distal sections having relatively rigid joint means for connection to the second pair of distal sections, and the second pair of distal sections having flexible resilient joint means for telescopically joining the relatively rigid joint means of the first pair of distal sections, thereby holding the first and second elongated U-shaped members together in a jumping hoop of a selected size, wherein the rigid joint means comprises elongated elements and wherein the flexible joint means comprises elongated rigid tubes having segmental openings spaced from ends of the tubes and having flexible round resilient bands circumferentially surrounding the tubes at the segmental openings and extending into the segmental openings, the elongated elements of the first rigid joint means being positioned in the tubes, the bands extending through the segmental openings to engage the elements, whereby relative longitudinal movement of the first and second joint means frictionally draws portions of the bands from the segmental openings to positions between the elements and inner walls of the tubes, tightly wedging the elements in the tubes, against further relative axial movement in the same direction.
Claim 3
Dependent Claim
13 words
The jumping hoop of claim 1 wherein the elements have cylindrical outer walls.
Claim 4
Dependent Claim
57 words
The jumping hoop of claim 2 wherein the bands comprise O-rings which have substantially line contact with the cylindrical outer walls of the elements, whereby angularly twisting of the elements and the tubes creates sliding friction between the elements and the O-rings, thereby permitting relative axial movement of the tubes and members without wedging the O-rings therebetween.
Claim 5
Dependent Claim
37 words
The jumping hoop apparatus of claim 1 wherein the first elongated member is a rigid U-shaped member, and wherein the second elongated member is a flexible member held in a U-shape by joining with the first member.
Claim 6
Dependent Claim
15 words
The jumping hoop of claim 1 wherein the second elongated member is a soft tube.
